Abstract
A global shutter image sensor of a back-illuminated type includes a semiconductor substrate and pixels. Each pixel includes a photosensitive area, a storage area, a readout area and areas for transferring charges between these different areas. The image sensor includes, for each pixel, a protector extending at least partly into the substrate from the back of the substrate to ensure that the storage area is protected against back illumination.
